Trueform Technology

Keysight TrueformGenerate true point-by-point arbitrary waveforms with less jitter, more fi delity and greater resolution

Over the past two decades, direct digital synthesis (DDS) has been the waveform generation technology of choice in function generators and economical arbitrary waveform generators. DDS enables waveform generators with great frequency resolution, convenient custom waveforms, and a low price.

As with any technology, DDS has intrinsic downsides and limitations as well. Engineers with exacting requirements have had to either work around the compromised performance or spend up to 10 times more for a high-end, point-by-point waveform generator. Keysight’s Trueform technology offers a new alternative that blends the best of DDS and point-by-point architectures, giving you the benefits of both without the limitations of either. Trueform technology uses an exclusive digital sampling technique that delivers unmatched performance at the same low price you are accustomed to with DDS.

Waveform sequencing (Available only on 33511B/12B/21B/22B)
Operation Individual arbitrary waveforms (segments) can be combined into user-defined lists (sequences)
to form longer, more complex waveforms. Each sequence step specifies whether to repeat
the associated segment a certain number of times, to repeat it indefinitely, to repeat it until a
Trigger event occurs, or to stop and wait for a Trigger event. Additionally, the behavior of the
Sync output can be specified in each step.
To improve throughput, up to 32 sequences totalling up to 1,024 segments can be pre-loaded
into volatile memory.
